Java: removing a specified number of elements from a queue

Question

I have to write a program that creates a queue of Strings. It asks the user to input a number n for which he will have to enter n number of names in the queue. Then until the queue is empty, the program

1. displays the name on top of the queue
2. asks the user a number of names to be deleted.
3. deletes the number of names specified
4. display the name(s) deleted

The program should use only the add(), remove(), isEmpty() and element() methods. Here is what I have come up with so far:

package lesson1;
import java.util.*;


public class MyClass1{

public static void main(String[] args) {

Queue <String> strings= new LinkedList<String>();


Scanner input= new Scanner(System.in);

System.out.println("Please enter the number of names, n.");
int n= input.nextInt();

System.out.println("Please enter " +n+ " names");

for(int i=0;i<n; i++){

    strings.add(input.next());

}

System.out.println("\nDisplaying the names:\n");
for(String object: strings){

    System.out.println(object);
}

      while(!strings.isEmpty()){
        System.out.println("The name in front of the queue is: " + strings.element());


        System.out.println("Please enter the number of names to be deleted:");
        int del= input.nextInt();

        for(int i=0; i<del; i++){

        System.out.println("Name removed:"+strings.remove(i));

       }
      }

  }

}

The problem is that it is printing false for the names being deleted because remove() is a boolean method. How can I fix this?

Answer 1

Both poll and remove returns the deleted object but poll does not throw exceptions if that the problem, no one of them return boolean.

for (int i = 0; i < del; i++) {
    System.out.println("Name removed:" + strings.poll());
}
